DTC Descriptor
DTC C0253: Centering ErrorCircuit/System Description
The usable output voltage range for the lateral accelerometer and yaw rate sensors is 0.25-4.75 volts. The scan tool will report zero lateral acceleration or yaw rate as 2.5 volts with no sensor bias present. The sensor bias compensates for sensor mounting alignment errors, electronic signal errors, temperature changes, and manufacturing differences.
Conditions for Running the DTC
The vehicle speed is greater than 40 km/h (25 mph).
Conditions for Setting the DTC
The vehicle has been driven for 10 minutes without completing steer angle centering.
Action Taken When the DTC Sets
| • | The EBCM disables the VSES for the duration of the ignition cycle. |
| • | The DIC displays the Service Stability System message. |
| • | The ABS/TCS remains functional. |
Conditions for Clearing the DTC
| • | The condition for the DTC is no longer present and the DTC is cleared with a scan tool. |
| • | The EBCM automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles. |
Diagnostic Aids
The following conditions can cause this concern:
| • | Improper steering alignment. |
| • | Internal yaw/lateral accelerometer failure. |
| • | EBCM internal failure. |

Circuit/System Verification
- With the scan tool perform the Steering Angle Sensor Calibration.
- Operate the vehicle within the conditions for setting the DTC. Verify DTC C0186, C0196,C0253, or C0710 are not set.
| ⇒ | If DTC C0186, C0196, or C0710 are set, refer to Diagnostic Trouble Code (DTC) List - Vehicle . |
| ⇒ | If only DTC C0253 set, replace the EBCM |
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
